This should work:
A = readmatrix('test_input_xyz.txt');
[sz1, sz2] = size(A);
A = reshape(A,[],1);
B = sdec2bin(A,12);
B = reshape(string(B),sz1,sz2);
writematrix(B,'2_complement_values.txt','Delimiter','tab')
Note that i attached a .m-file which is needed. I loaded it down from here:
I checked one sample here:
which worked for me - but check results, since you work with a function from the web - not an inbuilt Matlab function.
